For this, a co-culture of Aeromonas hydrophila strain AH-1N as an enzyme-releasing bacterium and of Flavobacterium sp. strain 4D9 as a bacterium with cell-associated enzymes was set up with chitin embedded into agarose beads to account for natural conditions, under which polymers are usually embedded in organic aggregates. In single cultures, strain AH-1N grew with embedded chitin, while strain 4D9 did not. In co-cultures, strain 4D9 grew and outcompeted strain AH-1N in the biofilm fraction. Experiments with cell-free culture supernatants containing the chitinolytic enzymes of strain AH-1N revealed that growth of strain 4D9 in the co-culture was based on intercepting N-acetylglucosamine from chitin degradation. For this, strain 4D9 had to actively integrate into the biofilm of strain AH-1N. This study shows that bacteria using different chitin degradation mechanisms can coexist by formation of a mixed-species biofilm.</dcterms:abstract> <dc:contributor>Jagmann, Nina</dc:contributor> <dc:rights>deposit-license</dc:rights> <dc:language>eng</dc:language> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-02-05T09:08:15Z</dcterms:available> <dcterms:bibliographicCitation>FEMS Microbiology Letters ; 326 (2012), 1. - S. 69-75</dcterms:bibliographicCitation> <dcterms:issued>2012-01</dcterms:issued> <dc:creator>Jagmann, Nina</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-02-05T09:08:15Z</dc:date> </rdf:Description> </rdf:RDF>
